Seco 17011837 Square End Mill 1in 6 Flute Cobalt SPC408

Product Description

The SECO 17011837 is a single-end, 6-flute cobalt square end mill designed for material removal and finishing operations in demanding machining environments. Built from M42 cobalt high-speed steel with a bright/uncoated finish, it delivers solid performance across a range of workpiece materials without the need for a coating. The tool measures 1 inch in diameter with a 6-inch length of cut and an 8.5-inch overall length. A 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces. Right-hand cut and right-hand flute orientation are standard. This end mill is suited for machinists, tool-and-die makers, and CNC operators working in production or job shop settings.

This end mill is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys. It is part of the SPC408 series, which is designed for long-reach roughing and finishing applications where a standard-length tool cannot reach the required depth of cut. The 6-inch length of cut makes it well suited for deep-pocket milling, profile work, and slotting operations where extended engagement is required. It is appropriate for both manual and CNC milling machines in job shop and production environments.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance in tough alloys
• 6 flutes for improved surface finish and higher feed rates compared to 4-flute designs
• 30-degree right-hand helix for efficient chip evacuation and reduced cutting forces
• 6-inch length of cut supports deep-pocket and extended-reach milling applications
• Center-cutting capable — supports plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for use with or without cutting fluid across multiple material types

Compatibility

Designed for use with standard milling machine spindles and CNC machining centers accepting a 1-inch straight shank. Compatible workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys (ISO material codes P, M, K, N, and S).

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the milling machine spindle is fully stopped and the machine is powered down or placed in an e-stop state before loading or removing the tool. Use a properly sized collet, end mill holder, or hydraulic chuck sized to the 1-inch shank diameter to maintain concentricity within the rated TIR of 0.0010 inches. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material; consult published speeds and feeds data for M42 cobalt at the applicable diameter.
